Question

Write a simplified expression, in terms of y, for both area and perimeter of the triangle below

Answer 1

Area:
`27y^(3) -24y^(2)`

Perimeter:
`6y^(2) +7y+5`

Explanation:

Area:

`(1)/(2)` x base x height

`6y^(2) ((1)/(2) )(9y-8)\\3y^(2) (9y-8)\\27y^(3) -24y^(2)`

Perimeter:

`6y^(2) +4y+(3y+5)\\6y^(2) +7y+5`
